Abstract
A method of generating a packet for low energy critical infrastructure monitoring (LECIM) wireless communication is provided. The method includes steps of generating a first bit string by multiplexing a physical layer header (PHR) bit and a physical layer service data unit (PSDU) bit; convolution encoding the first bit string; interleaving the convolution-encoded first bit string; generating a second bit string by multiplexing the interleaved first bit string with a synchronization header (SHR) bit; and modulating the second bit string with a frequency shift keying (FSK) method and a position-based FSK method.
